2022315 · Zinc-leaching residue (ZLR) with 0.46% Sn and 54% Pb brings potential threats to environment but is worthy to recover valuable metals. Reduction of Sn (IV) to Sn (II) is critical for tin extraction. In this work, selective extraction and recovery of tin from ZLR via oxalic acid/sulfuric acid leaching and hydrolytic precipitation was proposed.

202361 · Tin-coated copper-clad steel wire scrap is a high value-added tin-coated waste derived from the production and replacement of electronic products. The existing methods for the treatment of tin-coated waste present shortcomings, such as a large amount of waste liquid treatment, high equipment anticorrosion costs and low tin recovery rate.

2021213 · A new method for separating and recovering tin from a low-grade tin middling with high Si content and low Fe content by roasting with anthracite coal was researched by studying the reaction mechanism and performing an industrial test, in which the Sn was sulfurized into SnS(g) and then collected using a dust collector. The Fe-Sn …

20231219 · Tin (Sn) is a soft, non-toxic, highly malleable, rust and fatigue resistant metal. It is one of the few metals that has been used and traded by humans for more than 5000 years. Tin has a low melting point and alloys easily with other metals, thus enabling humans to combine tin with copper to make bronze, taking us from the Stone Age to the …

202171 · In this study, a low-temperature chlorinating process is proposed for tin recovery from the tin-containing slag by using ammonium chloride as the chlorinating reagent. Under the optimized chlorinating conditions, tin volatilization ratios of above 96% under both air and vacuum atmospheres could be achieved.

200311 · Various slags are produced as by-products in metallurgical processes or as residues in incineration processes. According to the origins and the characteristics, the main slags can be classified into three categories, namely ferrous slag, non-ferrous slag and incineration slag. Slags usually contain a quantity of valuable metals. They are actually a …

2024119 · Tin is a chemical element with the symbol Sn on the periodic table and atomic number 50. It is a silver-white, malleable, and relatively soft metal. Tin ore is typically found in nature in the form of minerals like cassiterite (tin dioxide), which is the primary source of commercially mined tin. For a metal, it has a relatively low melting ...
